Disclaimer: this entire subject is so meaningless, I half hate that I'm writing about it because we should really be focusing on the neofeudalists / tech-feudalists who are further corrupting an already dysfunctional government with a sinister agenda, not about if someone did or did not make a gesture with "enough" intent.

Why do you think the ADL didn't call it a nazi salute? What was different about Musk recently then, and what nation is he a vocal supporter of, much like the rest of the political party and president he's attached to?

I believe you'll find it more obvious that it's a case of selective bias to promote political causes they're attached to -- especially given that this is an organization that's called the "ok" hand gesture a nazi one, and generally calls anyone an antisemitic nazi if they so much as doubt if Israel is behaving justly.

Follow the money; follow the power.
